Lenovo debuted its first Linux-based laptops at LinuxWorld in San Francisco on Tuesday, running SUSE Linux Enterprise Desktop 10 provided through a partnership with Novell. The systems are the result of a two-year research effort by the two companies as well as Intel, whose Centrino Duo processors power the portable. The Thinkpad T60p is an inch thin and weighs 4.7 pounds. Several features of Lenovo's Windows-based notebooks, including Help Center support, the ThinkPad Configuration Utility, Power Manager and Access Connections have been ported to Linux, the company said.
